Network Automation Helps Secure the Network

A smart network puts control into the IT administrator's hands-all at the push of a button. Just as importantly, network automation is also used to secure the network.

For example, in a hotel, hospital or school where visitors might be tempted to unhook a voice over IP (VOIP) phone and connect their laptop to the network, the automated features prevents these users from gaining unauthorized access. They do this by identifying that it's no longer a VOIP phone attached and that the applications that run on the network port are no longer voice traffic.

The network automatically reenables the port after a few minutes to see if further change has occurred (such as the user reattaching the VOIP phone). The software continues to keep the port deactivated or quarantined if a laptop is still connected. This is yet another example of how automation erases the long-lasting headaches of a static network.

Whether it is the configuration and monitoring of phones, access points or users, these simple tasks add up quickly. By streamlining network tasks through automation, the network edge is automatic, accurate and simple-leaving the network staff to focus more proactively on critical endeavors of the business.
